International Standard VersionBut not everyone has this knowledge. Some people are so accustomed to idolatry that when they eat food that has been offered to an idol, their conscience becomes contaminated because it is weak.

American Standard VersionHowbeit there is not in all men that knowledge: but some, being used until now to the idol, eat as of a thing sacrificed to an idol; and their conscience being weak is defiled.

Young's Literal Translation but not in all men is the knowledge, and certain with conscience of the idol, till now, as a thing sacrificed to an idol do eat it, and their conscience, being weak, is defiled.
